Question

PLEASE HELP The diagram below shows the wavelengths and frequencies for the various regions of the electromagnetic spectrum.

Which of the following is true about the frequencies of electromagnetic radiation?
A.X-rays have lower frequencies than infrared waves.
B.
Gamma rays have lower frequencies than ultraviolet waves.
C.
Ultraviolet waves have higher frequencies than radio waves.
D.
Radio waves have higher frequencies than X-rays.

Answer 1

higher than the frequencies of radio waves.

Step-by-step explanation:

The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. The wavelength is the distance between peaks in the wave, or the distance from crest to crest. If a wave is passing by a point, the frequency is the time interval between passing peaks. Therefore as the wavelength increases, the frequency decreases (and vice-versa).

The frequencies of visible light waves are higher than the frequencies of radio waves and infrared waves. Visible light waves have frequencies that are lower than the frequencies of X-rays.

Answer 2

option C

Step-by-step explanation:

Actually the order of frequencies for various regions of the electromagnetic spectrum is

Gamma rays > X-rays >Ultraviolet waves > Visible light > Infrared radiation > Micro waves > Radio waves

So from this order of frequencies Gamma rays has the largest frequency and Radio waves has the least frequency

For the order of wavelengths, it is just opposite to the order of frequencies because from the formula c=(wavelength of the light)×(frequency of the light)

As the wavelength of the radio waves is more, it actually means that radio waves can travel a large distance and as the frequency of the Gamma rays is more it can penetrate easily through any body
